Answer:
a. iron-fortified infant rice cereal
Explanation:
It's okay to feed babies with foods that are rich in iron, but rice cereal is not always the best option. Still, out of the given choices, this one is the healthiest alternative. The rice cereal that is rich in iron is a good way to provide your baby with it, since they are born with reserves of it, but they start to use them once they're 6 months and older. Babies that are breastfed, need an alternative, as formula is rich in iron and parents wouldn't have to worry about it. The iron found in cereal is not absorbed well and that's why expert suggest that once a baby starts to eat solid food, it's better to feed them with poultry, tofu, red meat, beans, pasta, etc.
